Extracts from P seudomonas bacteria with high cyclic‐di‐GMP levels trigger reduced reactive oxygen species (ROS) burst. Total ROS accumulation in A rabidopsis thaliana (A–C) and N icotiana benthamiana (D, E) leaf discs after treatment with Pseudomonas extracts, expressed as relative light units (RLU) over 60 min. Leaf discs were treated with extracts from Pseudomonas syringae pv. tomato (Pto) DC3000 (A, D), P . protegens Pf‐5 (B, E) or P . aeruginosa  PAO1 (C, E) carrying empty p BBR 2 vector (WT), p BBR ‐wsp R 19 (wspR19), PAO1 Δyfi R or 1 μm purified cdG. Values are means ± standard error (n = 8). Asterisks indicate statistically significant difference (*P < 0.05; ***P < 0.001) between treatment of wild‐type extracts and other samples based on a two‐tailed Mann–Whitney test.
